This shapefile is the official boundary of the Eastern Brook Trout Joint Venture. The boundary was originally developed by the United States Fish and Wildlife Service and was updated in 2013 to reflect revisions from the Eastern Brook Trout Joint Venture, a recognized Fish Habitat Partnership (FHP) of the National Fish Habitat Partnership.

This ArcGIS Map Package contains information on brook trout occupancy in the southern portion of the brook trout range (PA and south). Fish sample data from a number of state and federal agencies/organizations were used to define patches for brook trout as groups of occupied contiguous catchment polygons from the National Hydrography Dataset Plus Version 1 (NHDPlusV1) catchment GIS layer. After defining patches, NHDPlusV1 catchments were assigned occupancy codes. Then state and federal agencies reviewed patches and codes to verify data accuracy. A similar effort is currently being conducted by the Eastern Brook Trout Joint Venture to develop occupancy data for the remainder of the brook trout range including states...

The dataset is composed of four tables containing data collected during screening surveys for invasive Round Goby (Neogobius melanostomus) at 12 sites on the Eastern Erie Canal in New York between Oneida Lake and the Hudson River from 2016 to 2023. The sampling techniques and frequency of sampling were adapted over time to optimize the efficiency of the study effort. From 2016-2019 eDNA water sampling and traditional fish surveys using seining, trapping, and benthic trawling were conducted twice annually (spring and summer) at the 12 sites. From 2020-2022, eDNA water sampling and traditional fish surveys using benthic trawling and electrofishing were conducted twice annually (spring and summer). In 2023, benthic...

ScienceBase brings together the best information it can find about USGS researchers and offices to show connections to publications, projects, and data. We are still working to improve this process and information is by no means complete. If you don't see everything you know is associated with you, a colleague, or your office, please be patient while we work to connect the dots. Feel free to contact sciencebase@usgs.gov.
